WordPress Image Optimization Plugin
Picture Optimizer's WordPress plugin compresses images, converts formats, writes AI metadata, and replaces files — directly from your Media Library. One plugin. Full pipeline.
The Processing Pipeline
Each image passes through five stages. The plugin automates every step.
Upload
The plugin sends your image to the processing server. Your WordPress server handles only the upload and download.
AI Analysis
The AI vision engine examines the image. It identifies objects, reads text, detects scenes, and writes alt text, title, caption, description, and a keyword-rich filename.
Compression
The compression engine re-encodes the image at your quality preset. It strips unnecessary metadata and produces the smallest file that preserves visual fidelity.
Format Conversion
If you selected WebP or AVIF as output, the engine converts the file using codec-specific encoding tuned for the image content.
File Replacement
The processed file downloads to your WordPress server. The plugin replaces the original, regenerates thumbnails, updates every URL reference, and adds redirect rules.
Everything the Plugin Handles
Bulk Processing
Select 500+ images from the Media Library. Process them in one batch with real-time progress tracking.
AI Metadata Generation
Alt text, titles, captions, descriptions, and filenames — all written by AI vision based on each image's actual content.
Smart Compression
Six quality presets. The engine selects quantization parameters per image for the tightest compression above your quality threshold.
Format Conversion
Convert JPG and PNG to WebP or AVIF. Each conversion applies format-specific encoding with correct MIME types.
URL Management
Every URL reference updates — post content, postmeta, widgets, theme settings. .htaccess redirects map old URLs to new files.
One-Click Revert
Every original is backed up. Revert any image — file, URLs, redirects, and metadata all restore with one click.
EXIF Embedding
AI-generated metadata embeds into EXIF, IPTC, and XMP fields. Metadata persists when images are downloaded elsewhere.
Pipeline Modes
Full Pipeline (analyze + compress), Analyze Only (metadata), or Compress Only (compression). Choose per batch.
Sample Preview
Preview compression results before committing credits. Free previews show file size and quality.
